New Text A he P e r m u t i t Mixed Bed Demineralizer is a single ion-exchange unit containing both anion a n d cation exchangers in homogenous mixture. This combination provides a maximum number of indi­ vidual demineralizing steps, so that mineral impu­ rities a r e reduced to the vanishing point. In fact, conventional water analysis methods cannot even determine accurately the minute remaining quan­ tities. T h e purity of such treated water must b e determined by conductivity and spectrophotome­ ter measurements. Mixed Bed Demineralizing units usually con­ tain P e r m u t i t Q, a sulfonated styrene type cation exchange resin. The anion exchanger most used is Permutit S, a highly basic- quarternary a m i n e anion exchange resin which removes acids includ­ ing silicic acid from solution. Now this useful treating method is available, designed for fully automatic operation by the fore­ most manufacturer of automatic water condition­ ing equipment. For further details, write to The Permutit Com­ pany, Department C N - 6 , 3 3 0 West 42nd Street, New York 3 6 , Ν. Υ.
